Sixteen years after its original release, Nelly's blockbuster debut album Country Grammar has finally been certified diamond by the RIAA. That's right, the St. Louis, Mo. rapper has officially moved 10 million units of his first album, which first came out back in 2000. He was surprised on stage on Monday night with a plaque commemorating his amazing accomplishment.

Country Grammar is just the eighth album in hip-hop history to achieve a diamond certification. Other diamond-selling albums include Eminem's The Marshall Mathers LP and The Eminem Show, Outkast's Speakerboxxx/The Love Below, Tupac's All Eyez On Me, and The Beastie Boys' Licensed to Ill.

Nelly's debut was an instant smash when it came out in 2000. It spawned major hits like "Country Grammar (Hot Shit)," "Ride Wit Me," and "E.I.," all of which made a big impact on the Billboard Hot 100 chart.

His Country Grammar plaque wasn't his only sales achievement of the night, either. Nelly was also honored with a diamond single plaque for his Florida Georgia Line collaboration "Cruise."

Huge congratulations to Nelly for his big accomplishment.
